Based on last nights guiding the re orientation is a winner but more nights are needed to quantify
Your obviously using a 50mm guide scope in the offset shoe bracket. I started with that option but changed to a centrally mounted 60mm guide scope on a solid mounting bar on the tube rings , much more rigid system especially with imaging focal lengths at 1000mm +
In regard to your elongated stars what are your Ra and Dec numbers ? Are they close in value or significantly different ?
Is your polar alignment tight ( less than 1 or 2 arc minutes )
Maybe you have some high Dec backlash ?
Try the guiding assistant in PHD2 it will give you plenty of data to evaluate any issues
